Revolutionizing lighting: Color-changing LEDs promise high-quality, energy-efficient illumination.

Color Constancy

The article explores how the color temperature of LED lights can impact our feelings and atmosphere. Researchers tested cool-white and neutral-white LEDs to see how they perform in terms of color temperature, color rendering, and chromaticity. They used different power supplies to vary the LED parameters and found that the cool-white LED had a peak wavelength of 445 nm, while the neutral-white LED had a peak wavelength of 598 nm. The goal was to design LEDs that are both energy-efficient and provide good color quality for various applications.
